BARREL-BUMP.

Specification of Letters Patent Application filed m 28, 1911. Serial No. 641,007.

vented V certain Improvements in Barrel- Pumps,-ofwhich the followingis a specification; 3

;My invention consists of certain improvements in pumps for forcing liquids which are used for spraying trees and plants for the prevention of injury thereto by insect pests, fungus 'rowths, or the like, and especially to such pumps as are used in connection with barrels in which the liquid is contained.

The object of my invention is to so construct such a pump that the working parts of the same are located on the outside of the barrel; that theapplication of the pump to the barrel or its removal therefrom can be readily efl'ected; that the valves are readily accessible, and that the operation of the pump will also effect the operation of an agitator whereby the liquid in the barrel will be kept in a constant state of motion while the pump is being operated and the settling on the bottom of the barrel of matter held in mechanical suspension in the liquid will thereby be prevented.

The figure shown in the accompanying drawings is a perspective view of a pump constructed in accordance with my invention, the barrel in connection with which the pump is used being shown by dotted lines.

In the drawing, 1 represents the pump cylinder, 2 the induction chest therefor, 3 the eduction chest, t the casing of the pressure chamber into which the pump discharges, 5 the suction pipe whose upper end communicates with the induction chest of the pump through a flexible hose 6 and other appropriate connections, and 7 the agitator for the liquid within the barrel.

The suction pipe 5, the agitator 7 and the arm 9 which carries the latter are located inside of the barrel and extend through a suitable opening in the top head of the same, all of the other parts of the pump being on the outside of the barrel and being secured thereto by means of a bracket 10 and hooked clamps 11, the bracket 10 being pivotally mounted upon a split clamp 12 which surrounds the casing 4 ofgthe pressure chamher and is secured thereto; and the clamps 11 hooking over the chine of the barrel and on a cap 15 which is secured to the top of the casing 4, as shown in the'figure, each of said stems 12-) being provided with a nut whereby the clamps 11 can be tightened and the the'cap 15 is adapted. so as to be free to swing therein. a rock shaft 20 which is connected to or formed in one piece with the upper end of the agitator-carrying arm 9, and to said rock shaft is secureda link 21, to whose upper end is pivoted the pump lever 22,'thc latter also havingp-ivotal connection-with the rod of thepunip plunger, the latter passing through a stuffing boxat the top of the pump cylinder 1.

The pump cylinder l. induetion'chest 2, and eduction chest are all cast in one piece with a base structure 26 having a threaded opening into which the lower end of the pressure chamber casing is is screwed.

As the pump handle 22 is vibrated. backward and forward swinewill be imparted to the link 21 to which said lever is hung and this will cause rocking movement of the shaft 20 which carries the arm 9 of the agitator 7, thereby causing the latter to swing to and fro in the barrel close to the bottom of the same, and thus stir up any solid matters which have been deposited on the bottom of the barrel and cause such mat ters to remain in mechanical suspension in the liquid contained in the barrel.

The suction pipe 5 is provided, at the bottom, with a strainer 4-1 of anv appropriate character, and the agitator 7 operates in proximity to this strainer so as to prevent the choking or clogging of the latter by the settlement of solid matter around the same.

In a pump such as that constituting the subject of my invention and having all of the parts except the suction pipe and agitator outside of the barrel, the working parts of the pump are readily accessible without removing the pump from the barrel, consequently repairs to the pump, such as the repacking of the stuffing box or the removal having stems 13 which pass through lugs 14' and replacin of a valve or valve seat, can be readily e ected. The pump can also be cheaply constructed, no machine work being required except the cutting of the threads for the screwing together of the various parts of which the pump is composed.

By pivoting the bracket 10 to the split clamp 12, said bracket is permitted to assume any desired angle necessary to adapt it to the bilge of the barrel to which the pump is applied.

In the term pumpin mechanism as used in my claims I inclu e all of the parts shown and described with the exce tion of the suction pipe but it should be un erstood that pumping mechanism of any desired character may be used without departing from the essential features of my invention.

. I claim:

1. The combination, in a barrel pump, of the barrel, pumping mechanism located outside of the barrel and disposed alongside of the same, a suction pipe connected to said pumping mechanism, but disposedon the inside of the barrel and entering said barrel from the top, and means for securing the pumping mechanism to the outside of the barrel, said means comprising a bracket secured externally to the barrel staves and a hooked clamp carried by the pumping mechanism and engaging the chine at the top of the barrel.

2. The combination, in a barrel pump, of the barrel, pumping mechanism located outside of the barrel and alongside of the same, a suction pipe connected to the pum ing mechanism but disposed on the inside 0 the barrel and entering the same from the top, and mechanism for securing the pumping mechanism to the outside of the barrel, said mechanis comprising a bracket secured externally to the barrel staves and having a pivotal connection with the pumping mechanism and a hooked clamp carried by the pumping mechanism and engaging the chine at the top of the barrel.

' 3. The combination, in a barrel pump, of the barrel, pumping mechanism outside of the barrel and including a pump lever and a pump plunger rod, an agitator within the barrel, a rock shaft carrying said agitator and projecting over the top of the barrel, and a link secured to said rock shaft and to which link the pump lever is pivoted, the said pump plunger rod being also connected to the pump lever and guided so'as to move in a straight line whereby as the plunger rod is reciprocated swinging move ment will be imparted to the link and rocking movement to the rock shaft carrying the agitator.

In testimony whereof, I have signed my name to this specification, in the presence f two subscribing witnesses.
